The tan dog with the black muzzle? Not sure, to me she doesn't look like a GSD. There are GSDs that are completely 'blonde' with black muzzles, but something else just seems off. Maybe others will be able to weigh in .... also, post more pictures when she's a bit older. Sometimes it's hard to really tell with puppies.
Murdock - GSD
Virgil, CGC - GSD
Tara, Reagan, Madison, and Jefferson - Aussies
